This is a reference card for the TikZ graphics language. I created it over ten years ago for my own use as a quick reference for the available options and their precise syntax. On seeing the name of an option, I can remember what it does, so the amount of explanation ranges from little to none. My intention was mainly to fit as much information as possible about TikZ syntax into two sides of paper.
The PDF and LuaLaTeX source code are available on Codeberg.
